Chemical Composition Analysis,Microstructure Analysis and Isolated Lignin Structural Characterization of Dendrocalamus membranaceus cv.grandis at Different Growth-ages
摘要
Abstract
In this study,the chemical composition,fiber morphology,biological structure,and lignin structure of three kinds of Dendrocala-mus membranaceus cv.grandis of different bamboo growth-ages were studied by field emission scanning electron microscopy,gel permeation chromatography and 2D nuclear magnetic resonance.The results showed that with the increase of bamboo growth-ages,the average length and width of bamboo fiber increased slightly,but the ratio of length-width remained unchanged.The proportions of fundamental tissue de-creased,proportions of fibrous tissue and conducting tissue increased.The fiber cell wall of the fiber strand in the bundle was thickened gradually.The hemicellulose,cold water and hot water extracted from the bamboo gradually decreased.Acid insoluble,acid soluble lignin,lignin content,and benzenol extract content increased.The lignin of different bamboo growth-ages was GSH type,and the main bonding mode between lignin structural units was β-O-4 ether bond.With the increase of bamboo age,the S/G value increased,the molecular weight of lignin increased,and the content of β-O-4 ether bond increased.关键词
